磁共振成像是目前医学成像技术中功能最强大,技术门槛最复杂的技术之一。然而,相对其他成像模态较为缓慢的采集速度(较长的扫描时间)制约了磁共振成像在临床上的广泛应用。借助采样样本的数量与扫描时间的正比关系,通过减少采集的数据量(稀疏采样)来缩短磁共振采集时间是磁共振成像领域的重要途径,而从高度欠采样的数据中重建出高质量的图像可以近似为一个病态反问题,对这一问题的求解是快速磁共振成像领域的研究热点。本次...
The usefulness of magnetic resonance spectroscopy (MRS)–based techniques for assessment of human body composition has not been established.
Antiretroviral therapy has improved the prospects for people infected with HIV, but some develop a syndrome of profound body habitus and metabolic alterations that include truncal enlargement.
The N M R spectroscopy of molecules undergoing rapid exchange between diamagnetic and paramagnetic environments is well understood and is exemplified in studies of fast electron transfer between an or...
The 5 5 13Cand 4 I5Nnmr transitions in chlorophyll a and its magnesium-free derivative pheophytin a have been assigned. Emphasis is placed on the quaternary carbon atoms of the macrocycle which carry ...
Fatty liver is a common metabolic disorder of dairy cows during the transition period. Historically, the diagnosis of fatty liver has involved liver biopsy, biochemical or histological examination of ...
The Surface Nuclear Magnetic Resonance (SNMR) method is a fairly new technique in geophysics to assess ground water, i.e. existence, amount and productibility by measurements at the surface. The NMR t...
In this work, the attention has been focused to the field of “medical imaging”. The problem of pattern recognition in remote sensing with medical application has been discussed in order to detect sign...
Osteochondritis dissecans (OCD) of the humeral head is a common cause of forelimb lameness in dogs. OCD represents the late phase of osteochondrosis (OC). Magnetic resonance imaging (MRI) is a useful ...
Magnetic resonance (MR) imaging has unparalleled soft-tissue imaging capabilities. The presence of devices such as pacemakers and implantable cardioverter/defibrillators (ICDs), however, is historical...
Biodiesel production has increased dramatically over the last decade, raising the need for new rapid and non-destructive analytical tools and technologies. 1 H Low Field Nuclear Magnetic Resonance (...
The aim of this study was to determine the influence of MHS-genotype and feeding regime on the growth and development of muscle and fatty tissue in the whole body as well as in hams of hybrid pigs. Th...
In present study, single quantum (SQ) and triple quantum filtered (TQF) 23Na magnetic resonance imaging (MRI) was used to monitor the severity and progression of CCl4 induced acute and chronic liver d...
This study describes a case of a six-year-old female crossbreed dog that had a three months history of progressive right thoracic limb lameness. Palpation revealed muscle atrophy of the scapular and h...
